reefer train.jpgAs of 1954, the PRR's "Makeup of Trains" consist books list show only PRR reefers used in the creation of passenger trains. With few exceptions, class R50b is prescribed. Videos and photos, however, show Railway Express Agency reefers in use as well, though to a lesser extent.

The following table was created from data contained in The Official Railway Equipment Register.
